Helicon (also transliterated Helikon) was a river of the Macedonian city Dion. There is also a river called Helikon [in Pieria]. After a course of seventy-five stades the stream hereupon disappears under the earth. After a gap of about twenty-two stades the water rises again, and under the name of Baphyras instead of Helikon flows into the sea as a navigable river. The people of Dion (Dium) say that at first this River flowed on land throughout its course. But, they go on to say, the women who killed Orpheus wished to wash off in it the blood-stains, and thereat the River sank underground, so as not to lend its waters to cleanse manslaughter.
